Knowledge of number theory and abstract algebra are pre-requisites for any engineer designing a secure internet-based system. However, most of the books currently available on the subject are aimed at practitioners who just want to know how the various tools available on the market work and what level of security they impart. These books traditionally deal with the science and mathematics only in so far as they are necessary to understand how the tools work. Internet Security differs by its assertion that cryptography is the single most important technology for securing the Internet. To quote one reviewer «if every one of your communication partners were using a secure system based on encryption, viruses, worms and hackers would have a very hard time». This scenario does not reflect the reality of the Internet world as it currently stands. However, with security issues becoming more and more important internationally, engineers of the future will be required to design tougher, safer systems. Internet Security: * Offers an in-depth introduction to the relevant cryptographic principles, algorithms protocols – the nuts and bolts of creating a secure network * Links cryptographic principles to the technologies in use on the Internet, eg. PGP, S/MIME, IPsec, SSL TLS, Firewalls and SET (protecting credit card transactions) * Provides state-of-the-art analysis of the latest IETF standards plus summaries and explanations of RFC documents * Authored by a recognised expert in security Internet Security is the definitive text for graduate students on security and cryptography courses, and researchers in security and cryptography areas. It will prove to be invaluable to professionals engaged in the long-term development of secure systems.

The development of connected, communicating objects is showing no signs of slowing down. With an increasing number of objects available on the market, the evolution of the Internet of Things is leading to more and more fields being explored via information and communication sciences. This book analyzes the ecosystem of the Internet of Things by retracing the historical and technological context of the Internet's evolution from traditional to dynamic, social and semantic, and then towards this ecosystem of connected objects. The evolution of concepts surrounding the Internet of Things is explored via real-life examples of connected objects; both those used for specific functions and for more general everyday objects. Numerous issues associated with these new technological and digital transformations in a «hyperconnected» world, as well as the impact of the massive influx of connected objects, are discussed. The crucial questions of potential intrusion into the private lives of users as well that of security are then studied.

This book addresses researchers and graduate students at the forefront of study/research on the Internet of Things (IoT) by presenting state-of-the-art research together with the current and future challenges in building new smart applications (e.g., Smart Cities, Smart Buildings, and Industrial IoT) in an efficient, scalable, and sustainable way. It covers the main pillars of the IoT world (Connectivity, Interoperability, Discoverability, and Security/Privacy), providing a comprehensive look at the current technologies, procedures, and architectures.

Internet of Things: Connecting Objects… puts forward the technologies and the networking architectures which make it possible to support the Internet of Things. Amongst these technologies, RFID, sensor and PLC technologies are described and a clear view on how they enable the Internet of Things is given. This book also provides a good overview of the main issues facing the Internet of Things such as the issues of privacy and security, application and usage, and standardization.

The mobile industry for wireless cellular services has grown at a rapid pace over the past decade. Similarly, Internet service technology has also made dramatic growth through the World Wide Web with a wire line infrastructure. Realization for complete wired/wireless mobile Internet technologies will become the future objectives for convergence of these technologies through multiple enhancements of both cellular mobile systems and Internet interoperability. Flawless integration between these two wired/wireless networks will enable subscribers to not only roam worldwide, but also to solve the ever increasing demand for data/Internet services. In order to keep up with this noteworthy growth in the demand for wireless broadband, new technologies and structural architectures are needed to greatly improve system performance and network scalability while significantly reducing the cost of equipment and deployment. Dr. Rhee covers the technological development of wired/wireless internet communications in compliance with each iterative generation up to 4G systems, with emphasis on wireless security aspects. By progressing in a systematic matter, presenting the theory and practice of wired/wireless mobile technologies along with various security problems, readers will gain an intimate sense of how mobile internet systems operate and how to address complex security issues. Features: Written by a top expert in information security Gives a clear understanding of wired/wireless mobile internet technologies Presents complete coverage of various cryptographic protocols and specifications needed for 3GPP: AES, KASUMI, Public-key and Elliptic curve cryptography Forecast new features and promising 4G packet-switched wireless internet technologies for voice and data communications Provides MIMO/OFDMA-based for 4G systems such as Long Term Evolution (LTE), Ultra Mobile Broadband (UMB), Mobile WiMax or Wireless Broadband (WiBro) Deals with Intrusion Detection System against worm/virus cyber attacks The book ideal for advanced undergraduate and postgraduate students enrolled in courses such as Wireless Access Networking, Mobile Internet Radio Communications. Practicing engineers in industry and research scientists can use the book as a reference to get reacquainted with mobile radio fundamentals or to gain deeper understanding of complex security issues.

Discusses the evolution of WHOIS and how policy changes will affect WHOIS’ place in IT today and in the future This book provides a comprehensive overview of WHOIS. The text begins with an introduction to WHOIS and an in-depth coverage of its forty-year history. Afterwards it examines how to use WHOIS and how WHOIS fits in the overall structure of the Domain Name System (DNS). Other technical topics covered include WHOIS query code and WHOIS server details. The book also discusses current policy developments and implementations, reviews critical policy documents, and explains how they will affect the future of the Internet and WHOIS. Additional resources and content updates will be provided through a supplementary website. Includes an appendix with information on current and authoritative WHOIS services around the world Provides illustrations of actual WHOIS records and screenshots of web-based WHOIS query interfaces with instructions for navigating them Explains network dependencies and processes related to WHOIS utilizing flowcharts Contains advanced coding for programmers Visit the book's companion website http://whois.knujon.com for technical and policy documents concerning WHOIS, WHOIS code examples, internet locations for WHOIS databases and more. WHOIS Running the Internet: Protocol, Policy, and Privacy is written primarily for internet developers, policy developers, industry professionals in law enforcement, digital forensic investigators, and intellectual property attorneys. Garth O. Bruen is an Internet policy and security researcher whose work has been published in the Wall Street Journal and the Washington Post. Since 2012 Garth Bruen has served as the North American At-Large Chair to the Internet Corporation of Assigned Names and Numbers (ICANN). In 2003 Bruen created KnujOn.com with his late father, Dr. Robert Bruen, to process and investigate Internet abuse complaints (SPAM) from consumers. Bruen has trained and advised law enforcement at the federal and local levels on malicious use of the Domain Name System in the way it relates to the WHOIS record system.
